Abstract (en)
[origin: EP2253410A1] In joining a magnesium alloy material 1 (first material) and a steel material (second material), a zinc-plated steel plate 2 plated with zinc (metal C) is used as a steel material, Al (metal D) is added to the magnesium alloy material 1. Next, eutectic melting of Mg and Zn is caused so as to remove a product produced by the eutectic melting with an oxide film If and impurities from a joint interface. Moreover, an Al-Mg system intermetallic compound such as Al 3 Mg 2 and an Fe-Al system intermetallic compound such as FeAl 3 are produced, whereby regenerated surfaces of both materials 1 and 2 are joined via a compound layer 3 containing those intermetallic compounds.
